TEST SMARTER, NOT HARDER: PRACTICAL dbt TESTING FOR ANALYTICS TEAMS
Andrea Hronska Huzvarova, Analytics Engineer, Infinite Lambda

We have all been there: a dashboard breaks, you are the last one to know, and now you are in a rush to appease stakeholders and fix it. Let me show you a better way.
In the world of analytics engineering, tests are your first line of defence, helping you move from reactive fixing to proactive data quality.
In this session, you will learn how to use dbt, the best-in-class tooling for ensuring data quality. We will cover:

• Smart testing: going beyond unique and not_null tests without over-engineering;
• The dbt ecosystem: packages like dbt-utils and dbt-expectations that save you hours of manual work;
• Real-world application: a hands-on walkthrough of a sample project, showing you how and when to implement custom tests.

Come and see how clean, automated testing can build total confidence in your data.

MAKING AI EXPLAINABLE
David Thorvaldsen, AI/ML Data Scientist, Caterpillar

As data people, we need to be crystal clear on what goes on under the hood of the AI models we implement.
In this session, we will explore Layerwise Relevance Propagation (LRP), a cutting-edge technique that makes AI models understandable, interpretable, and clear in how they work.
We will use GenAI with GitHub Copilot to create an interactive Graphical User Interface (GUI) app for an easy-to-follow demo.
